We should upgrade gRPC. There are a number of perf improvements, for example:

codec: Implement a new Codec which uses buffer recycling for encoded message (#7356)
introduce a mem package to facilitate buffer reuse (#7432)
client: Improve RPC performance by reducing work while holding a lock (#7132)
*: Allow building without x/net/trace by using grpcnotrace to enable dead code elimination (#6954)
rand: improve performance and simplify implementation of grpcrand by adopting math/rand's top-level functions for go version 1.21.0 and newer. (#6925)
grpc: skip compression of empty messages as an optimization (#6842)
orca: use atomic pointer to improve performance in server metrics recorder (#6799)
client & server: Add experimental [With]SharedWriteBuffer to improve performance by reducing allocations when sending RPC messages. (Disabled by default.) (#6309)
server: improve stream handler goroutine worker allocation when NumStreamWorkers is used (#6004)

136558: rpc: add BenchmarkGRPCPing r=tbg a=tbg

This benchmarks simple unary requests across a gRPC server with
CockroachDB-specific settings (snappy compression, etc).

The benchmarks show a problematic amount of allocations especially
at small payload sizes, which is likely a common case in CRDB.

We also see that it's highly beneficial to reuse RPC streams, i.e.
to use bidirectional streaming RPCs to implement unary request-response RPCs.
This is because gRPC implements unary RPCs using one-off streams, which
incurs high overhead. I would liken it to CockroachDB using DistSQL for point
lookups.
